Topic: Is my pH OK? (Read 1004 times)

Brewed up 15 gallons of 1.103 Imperial Stout 5 weeks ago. Pitched a good amount of yeast but probably should have used more. Fermentation went well for a week, then died down. I racked after 2.5 weeks and it was only at 1.040. Added a pack of S-05 and it's still fermenting but it's only down to 1.35 at this point. My pH is 4.6. Is this OK? I plan on leaving it for another 2 weeks or so at the minimum but was wondering if the pH was slowing things down. I expected the SG to be much lower after 5 weeks.

Thanks guys, I'll leave it be. I have the ambient temp up to 72F. I started at 63F and let the ambient rise to about 68F. I bumped up the temp after racking. I only had 6.2% C-malts and mashed at 131 & 150 so I fully expect to get into the low 20's. I used lactic acid to get my water (for RIMS and sparge) down to a 5.4 pH range before mashing. Probably don't need to do that when I use a good amount of roasted malts. I'll check it a few weeks and pitch some CBC1 if I feel I need to get it any lower...
